HANDLEY PAGE (READING) MARATHON • Origin ally a Miles design, this short- and medium-range feederline transport carries 18-22 passengers. Three Marathons were de livered to West African Airways in October, 1952, and machines of this type are also operated by Union of Burma Airways. Marathon 1 (four Gipsy Queen 70-4, total 1,380 h.p.).—Span, 65ft; length, 52ft i|in; wing area, 498 sq ft; gross weight, 18,000 lb; wing loading, 36.14 lb/sq ft; range, 810 miles at 167 m.p.h. at 5,000ft with 4,260 lb payload. VICKERS-ARMSTRONGS VISCOUNT 700 • Developed by Vickers in close collaboration with B.E.A., the Viscount is to enter scheduled service on the London-Nice-Rome-Athens- Istanbul route in but a few weeks' time. As the world's first turboprop airliner, the Viscount has been the subject of much interest among potential operators, and this has been reflected in orders from Air France, Trans Canada Airlines, T.A.A. and Aer Lingus, in addition to the 26 for B.E.A. The Corporation's exten sive series of experimental proving flights and trial passenger services have shown a marked economy and reliability from Viscount operations, while from the passenger viewpoint the smoothness of flight and the wide-visibility windows are of excep tional appeal. Normal seating is for 48, with provision for up to 62 on tourist services. V.C. 2 Viscount 700 Series (four Dart R.Da 3, total, 5,400 h.p. -t-1,460 lb thrust)—Span, 93ft 8Jrin; length, 81ft 2in; wing area, 963 sq ft; gross weight, 58,500 lb; wing loading, 60.75 lb/sq ft; range, 800 miles at 300 m.p.h. at 20,000ft with 13,600 lb payload. VICKERS-ARMSTRONGS VISCOUNT 800 • For future high-density services over the shorter stage-lengths, this Viscount development has already been ordered (12 machines, plus an option on eight more), by B.E.A. With more powerful Dart power units, and a longer fuselage, the 800 will carry from 66 to 82 passengers—the Corporation's layout featuring probably 73 seats. Delivery is expected in 1955. V.C. 2 Viscount 800 Series (four Dart R.Da 5, total 6,160 h.p. -*-1,600 lb thrust)—Span, 93ft 8£in; length, 94ft 6in; wing area, 963 sq ft; gross weight, 65,000 lb; wing loading 67.5 lb/sq ft; range, 500 miles at 290 m.p.h. at 16,000ft with 15,000 lb payload. VICKERS-ARMSTRONGS VIKING • Designed as an interim-type aircraft to fill the immediate post-war gap, the Viking has performed steady service for B.E.A., the independents and other airlines since its introduction in 1946. Early Mk iA and 1 types were followed in 1947 by the "long-nosed" iB, which became the standard version. A total of 115 machines of this type were manufactured, including one experimentally fitted with Rolls-Royce Nene turbojets. Latest development in B.E.A. service is the Admiral-class conversion, which has increased the capacity from 27 seats to 38 for tourist operation. V.C.I Viking (two Hercules 634, total 3,380 h.p.).—Span, 89ft 3m; length, 65ft 2in; wing area, 882 sq ft; gross weight, 34,000 lb; wing loading, 38.5 lb/sq ft; range, 1,130 miles at 210 m.p.h. at 8,000ft with 7,75° lb payload.

HUREL-DUBOIS HD-31 and 32 • First flown on January 27th the HD-31, is the prototype of a cargo-carrying transport with wings of unusually high aspect ratio (20.2). It has been developed from the successful single-seat HD-10. Great economy and simplicity of operation are expected from the more powerful HD-32, now under construction, which will carry up to 42 passengers, or 11,025 lb freight payload. HD-32 (two R-1830 Twin Wasps, total 2,400 h.p.).—Span, 147ft 7"*; length, 72ft iin; wing area, 1,076.4 sq ft; gross weight (freight1), 38,260 lb; range, 1,240 miles at 168 m.p.h. at 10,000ft with 8,820 lb freight. S.N.C.A.S.E. 161 LANGUEDOC • Of pre-war design, the first Languedoc flew in 1939, but production was not continued until after the liberation of France. With initially 40 Languedocs in its fleet, Air France has since flown an impressive total of hours on the type, and still retains 15. S.E. 161 Languedoc (four Pratt and Whitney Twin Wasps, total 4,880 h.p.).—Span, 96ft 5in; length, 79ft 7in; wing area, 1,198 sq ft; gross weight, 45,360 lb; wing loading, 37.86 lb/sq ft; range, 1,420 miles at 233 m.p.h. at 7,500ft with 8,100 lb payload.

Auriol, possesses a specially equipped Bretagne for his personal use, and other operators include Air- Algerie, Air Maroc and S.T.A.E-O. S.O. 30 P-i Bretagne (two Pratt and Whitney R-2800 B43, total, 4,000 h.p.).—Span 88ft 2in; length, 62ft 2in; wing area, 928 sq ft; gross weight, 43,000 lb; wing loading, 46.4 lb/sq ft; range, 620 miles at 258 m.p.h. at 20,000ft with 8,200 lb payload. JUNKERS Ju 52/3M • This ageing three-engined German machine is still to be found carrying passengers, mail and freight on the minor air routes of the world.
